What is the percentage of people who need to be immune against COVID-19 in order to achieve herd immunity?
See full answerWe are still learning about immunity to COVID-19.
Most people who are infected with COVID-19 develop an immune response within the first few weeks, but we don’t know how strong or lasting that immune response is, or how it differs for different people.
There have also been reports of people infected with COVID-19 for a second time.
Until we better understand COVID-19 immunity, it will not be possible to know how much of a population is immune and how long that immunity last for, let alone make future predictions.
These challenges should preclude any plans that try to increase immunity within a population by allowing people to get infected..
Can COVID-19 be transmitted through feces or urine?
SARS-CoV-2 RNA has also been detected in other biological samples, including the urine and feces of some patients. One study found viable SARS-CoV-2 in the urine of one patient. Three studies have cultured SARS-CoV-2 from stool specimens. To date, however, there have been no published reports of transmission of SARS-CoV-2 through feces or urine.
Are people with underlying health conditions more at risk of getting COVID-19?
There is increasing evidence that people with existing chronic conditions or compromised immune systems due to disability are at higher risk of death due to COVID-19.
What food should you avoid during COVID-19?
• When cooking and preparing food, limit the amount of salt and high-sodium condiments (e.g. soy sauce and fish sauce). • Limit your daily salt intake to less than 5 g (approximately 1 teaspoon), and use iodized salt. • Avoid foods (e.g. snacks) that are high in salt and sugar. • Limit your intake of soft drinks or sodas and other drinks that are high in sugar (e.g. fruit juices, fruit juice concentrates and syrups, flavoured milks and yogurt drinks).• Choose fresh fruits instead of sweet snacks such as cookies, cakes and chocolate.
How is the presence of COVID-19 detected in testings?
Infection with the virus causing COVID-19 (SARS-CoV-2) is confirmed by the presence of viral RNA detected by molecular testing, usually RT-PCR. Detection of viral RNA does not necessarily mean that a person is infectious and able to transmit the virus to another person.
How long does it take to produce antibodies to fight the coronavirus disease?
See full answerThere is another, more common type of rapid diagnostic test marketed for COVID-19; a test that detects the presence of antibodies in the blood of people believed to have been infected with COVID-19. Antibodies are produced over days to weeks after infection with the virus. The strength of antibody response depends on several factors, including age, nutritional status, severity of disease, and certain medications or infections like HIV that suppress the immune system.In some people with COVID-19, disease confirmed by molecular testing (e.g. reverse transcription polymerase chain reaction: RT-PCR), weak, late or absent antibody responses have been reported. Studies suggest that the majority of patients develop antibody response only in the second week after onset of symptoms.
Does heat prevent COVID-19?
FACT: Exposing yourself to the sun or temperatures higher than 25°C DOES NOT protect you from COVID-19. You can catch COVID-19, no matter how sunny or hot the weather is. Countries with hot weather have reported cases of COVID-19.
What are the dangers of smoking my waterpipe during the coronavirus disease pandemic?
The main ingredient used in waterpipe is tobacco, and its use has both acute and long-term harmful effects on the respiratory and cardiovascular systems  , likely increasing the risk of diseases including coronary artery disease and COPD .The communal nature of waterpipe smoking means that a single mouthpiece and hose are often shared between users, especially in social settings . In addition, the waterpipe apparatus (including the hose and chamber) itself may provide an environment that promotes the survival of microorganisms outside the body.
Can the coronavirus disease spread through sewage?
There is no evidence that the COVID-19 virus has been transmitted via sewerage systems with or without wastewater treatment.
What is the incubation period of the coronavirus disease?
The incubation period of COVID-19, which is the time between exposure to the virus and symptom onset, is on average 5-6 days, but can be as long as 14 days. Thus, quarantine should be in place for 14 days from the last exposure to a confirmed case.
Can the coronavirus spread via feces?
There is some evidence that COVID-19 infection may lead to intestinal infection and be present in faeces. However, to date only one study has cultured the COVID-19 virus from a single stool specimen. There have been no reports of faecal−oral transmission of the COVID-19 virus to date.
Is a smoker at a higher risk of getting the COVID-19 virus than that a non-smoker?
See full answerAt the time of preparing this Q&A, there are no peer-reviewed studies that have evaluated the risk of SARS-CoV-2 infection associated with smoking. However, tobacco smokers (cigarettes, waterpipes, bidis, cigars, heated tobacco products) may be more vulnerable to contracting COVID-19, as the act of smoking involves contact of fingers (and possibly contaminated cigarettes) with the lips, which increases the possibility of transmission of viruses from hand to mouth. Smoking waterpipes, also known as shisha or hookah, often involves the sharing of mouth pieces and hoses, which could facilitate the transmission of the COVID-19 virus in communal and social settings.
Can the coronavirus disease be transmitted in hot or humid climates?
From the evidence so far, the COVID-19 virus can be transmitted in ALL AREAS, including areas with hot and humid weather. Regardless of climate, adopt protective measures if you live in, or travel to an area reporting COVID-19. The best way to protect yourself against COVID-19 is by frequently cleaning your hands. By doing this you eliminate viruses that may be on your hands and avoid infection that could occur by then touching your eyes, mouth, and nose.
Can drinking alcohol help in preventing COVID-19?
Alcohol does not protect against COVID-19; access should be restricted during lockdown.
Does the presence of antibodies mean that a person is COVID-19 immune?
There are many studies underway to better understand the antibody response following infection to SARS-CoV-2. Several studies to date show that most people who have been infected with SARS-CoV-2 develop antibodies specific to this virus. However, the levels of these antibodies can vary.
What should I do if I feel unwell during the COVID-19 pandemic?
See full answer• Know the full range of symptoms of COVID-19. The most common symptoms of COVID-19 are fever, dry cough, and tiredness. Other symptoms that are less common and may affect some patients include loss of taste or smell, aches and pains, headache, sore throat, nasal congestion, red eyes, diarrhoea, or a skin rash.• Stay home and self-isolate even if you have minor symptoms such as cough, headache, mild fever, until you recover. Call your health care provider or hotline for advice. Have someone bring you supplies. If you need to leave your house or have someone near you, wear a medical mask to avoid infecting others.• If you have a fever, cough and difficulty breathing, seek medical attention immediately. Call by telephone first, if you can and follow the directions of your local health authority.• Keep up to date on the latest information from trusted sources, such as WHO or your local and national health authorities.
How dangerous is the coronavirus disease?
Although for most people COVID-19 causes only mild illness, it can make some people very ill. More rarely, the disease can be fatal. Older people, and those with pre- existing medical conditions (such as high blood pressure, heart problems or diabetes) appear to be more vulnerable.
Is temperature screening effective to detect the coronavirus disease?
See full answerTemperature screening alone, at exit or entry, is not an effective way to stop international spread, since infected individuals may be in incubation period, may not express apparent symptoms early on in the course of the disease, or may dissimulate fever through the use of antipyretics; in addition, such measures require substantial investments for what may bear little benefits. It is more effective to provide prevention recommendation messages to travellers and to collect health declarations at arrival, with travellers’ contact details, to allow for a proper risk assessment and a possible contact tracing of incoming travellers.
